Effects of zectran spraying on forest birds and frogs in New Brunswick / P.A. Pearce, Anne Meachem Rick.: CW69-37/18E-PDF
"Two 3000-acre forest plots in south-central New Brunswick were aerially sprayed to control spruce budworm in early June, 1969. The two treatments were 4 1/2 days apart, and each was at an emission rate of 1 oz Zectran in 0.15 U.S.G./acre. Songbird censuses, post-spray searching for casualties, nest histories, and the behaviour of captives, all suggested no serious effects on birds. Counts of frogs and survival rates of caged tadpoles also suggested no serious effects on these forms attributable to Zectran, but some tadpole mortality was attributed to the fuel oil used in the formulation"--Abstract.
